The DIN cable is “Keyed” to prevent
misalignment and all connections are
gender specific
Leave the end caps on when routing to
prevent damage or contamination to the
leads. The cap is designed for pulling
through wire conduits.
The blue connector cap ends can be
discarded if a smaller diameter is
required such as a Pod mount. Use
shrink tube to seal the connections.
(Connector cap ends removed)
Before drilling holes for cable runs be sure there is sufficient room
behind the area. Always disconnect power before drilling around
electrical connections.
